This video shows the steps of how we do endoscopic balloon dilation of acquired subglottic stenosis in pediatrics.
The video has subtitles with all important steps.
Airway balloon use is safe and less traumatic to airway mucosa.
Adding adjunct kanacort and mitomycin might decrease the restenosis chance.
Membranous subglottic or tracheal stenosis.
Not thick and not long scars.
Not fit for general anesthesia
Grade IV stenosis
Loss of airway framework
Rigid laryngoscopy with suspension.
Laryngeal crocodile
Butterfly needle
Laryngeal round-knife
Balloon dilation set (CRE Pulmonary, Pulmonary Balloon Dilation Catheter, Boston Scientific, size 10 mm with pressure of 9 atm and duration of balloon was 1 minute)
Long term steroid injection
Mitomycin c
Rigid laryngoscopy with suspension.
Spontaneous breathing aided by side port insufflation.
Any major comorbidities like cardiorespiratory disease.
Could do pulmonary function test
N/A
Lung barotrauma in lightly sedated patients.
Watermelon seeding of the balloon which might cause pulmonary edema.
Saline aspiration.
None
